Sum (Σ) outputs are provided for each bit and a
resultant carry (C4) is obtained from the fourth bit.
This adder features full internal look ahead across
all four bits. A 4 x n binary adder is easily built up
by cascading without any additional logic.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
DESCRIPTION
The M74HC283 is an high speed CMOS 4 BIT
BINARY FULL ADDER fabricated with silicon gate
C MOS technology.
